990dba6498 clk: clk_stm32f: Fix PLLSAICFGR_PLLSAIP_4 divider value
PLLSAIP divider uses 2 bits (bits 16 and 17) into RCC_PLLSAICFGR
register, available combination are :
  00: PLLSAIP = 2
  01: PLLSAIP = 4
  10: PLLSAIP = 6
  11: PLLSAIP = 8

Previously, the divider value was incorrectly set to 6.

20fe38e75a clk: clk_stm32f: Move SYSCFG clock setup into configure_clocks()
Move SYSCFG clock setup into configure_clocks() instead of calling
clock_setup() from board file.

As this clock is only needed in case of ethernet enabled and as
both stm32f4 and stm32f7 are using the Designware ethernet IP,
we use CONFIG_ETH_DESIGNWARE to only enable this clock if needed.

Move the RMII setup from board_early_init_f() to board_init()
to insure that RMII bit is set only when clock driver is initialized.

cb97ff9d3d clk: stm32: retrieve external oscillator frequency from DT
All current STM32F4 supported boards uses a 8MHz external oscillator.
All current STM32F7 supported boards uses a 25MHz external oscillator.

In order to introduce the new stm32f429-evaluation board which uses a
25MHz external oscillator without creating a dedicated struct
stm32_clk_info for this board, retrieve the external oscillator
frequency from DT and set pll_m accordingly to obtain 1MHz for the VCO.
